What happens when you send a PC cooling expert such as Zalman into the field of PSUs? You get PSUs with genuine innovation in cooling, which translates to quieter PSUs. Such is the case of the ZM750-HP Plus, an upper-mid range 750W PSU from Zalman. The PSU replaces aluminum cooling plates with copper heat pipes that draw heat away from hot parts (such as FETs), and onto aluminum fin stacks, which are ventilated by a large 140 mm fan. Since a lot of heat is dissipated passively by these large heatsinks, the fan has very little work to do, and so it spins at low speeds, resulting in very quiet operation.

The ZM750-HP Plus features modular cabling, enough to wire out a gaming PC with two graphics cards. The PSU is 80 Plus Silver-rated. It uses a quad 12V rail design, among which two deliver 28A each (for graphics cards), one delivers 25A (motherboard and SATA), one delivers 20A (CPU, dedicated to the EPS connector). It uses a dual forward-switching design, with active PFC. A secondary protection IC governs various safety features such as OCP, OVP, SCP, UVP, and OTP. The ZM750-HP Plus from Zalman, is expected to be priced at US $189,50.
